The SPC rear camber −0.50° shim supplies a fixed negative camber change in −0.50° increments for vehicles with twist-beam rear axles. It installs as a full-contact shim and can be combined with toe shims to achieve the exact camber and toe balance required. Up to two shims may be stacked per side when a larger overall change is necessary.
